rrrnnosrarro secretaries awn eranante Be it known that 1, DAVID F. VoLLMER, a citizen of the United States, residing at Monroe, in the parish of Ouachita and State of Louisiana, have invented certain new and useful Improvements in Hydrostatic Propelling and Steering Apparatus, of-which the following is a specification.

My invention has relation to new and useful improvements in hydrostatic steering and propelling apparatus to be used in connection with a boat.

The main object of my invention is to produce an efficient means whereby a boat may be turned around in the water, without having any forward or rearward motion, whatmay be used for propelling a boat in the water. It is observed that in my apparatus Specification of Letters Patent. application file :1 they 21, .1908. Serial Ne. $84,667.

the water is drawn in at. the central portions of the sides of said boat, and is shot out through jets forwardly or rearwardly, or both, thus making it possible to control the boat no matter what position it may assume.

With these and other objects in View my invention consists in the novel construction and arrangement of part's' as are hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed In the, accompanying drawings which illustrate the preferred embodiment of my invention ;--The figure of the drawing illustrates a dia rammatic, horizontal, sectional view of mycat, and the apparatus used in connection therewith, showing the arrangement of the hydrostatic propelling and steering mechanism.

Referring more particularly to the draw ings my invention is described as follows The boat 1, which is adapted to have my apparatus installed therein, has the parallel longitudinal pipes 2, terminating at the rear end of said boat in propelling jets 3, and turning outwardly at their forward ends,

ingsteering jets at, and 4 Communicating with said pipes 2, and at right angles thereto are the ipes 5, which terminate at the sides of sald boat forming jets 6 and 6 The 7, which runs at right angles to the longlt dinal pipes, has its ends terminating at the sides of said boat, forming suction jets 8 and 8 Interrupting said pipe 7 near each of its ends are the pumps 9, said pumps hang of any desired or preferred form, A

which may be adapted for this purpose. Said pipes 2, 5, and 7, are provided With a number of gate valves 10, a number of check valves ll, and a number of hand valves 12,-

13, l 17 and 18. Said ate valvesare for the purpose of shutting off the flow of water through said pipes, when my apparatus is out of condition, or in need of repairs. The check valves are for the purpose of preventing the influx or outflow of water in said pipes, whichever the case may be. Said hand valves, are not necessarily regulated by hand, but may be operated from the pilot house by means of steam or electricity, or

any other mode of power, which may be adapted for-this purpose. These valves may be placed wherever needed, and are for the purpose of regulating my steering or propelling apparatus. Should it be desired to turn the boat to the right, then said valve 13, would be shut off, together with hand valve 14, while water is shot out through the jets al and 6; of course, if the boat is standing still, hand valve 17 and '18, will also be closed. It is thought that this explanation will suflice in making the operation of my invention clear to those versed in this art.

Though I have particularly described my invention, I may exercise the right to make such alterations and modifications therein aswill not depart from the spirit or scope of my invention.

Having described my invention, What I claim as new and desire to secure by Letters Patent. is

1. In a hout steering and propelling api paratus, the combination of two parallel,

longitudinal pipes terminating at their rear ends in propelling-jets, their front ends turned outwardly forming steering jets, with a pipe running at right angles to said longitudinal pipes and communicating with the same, said pipe provided with pumps adapted and for the purpose of drawing water into said pipes, said longitudinal pipes further provided near their rear ends with pipes at right angles thereto and communicating therewith, said last mentioned pipes terminating in steering-jets, all of said pipes provided with a series of valves, adapted and for the purpose of enabling the efficient operation of said apparatus.

2. In a boat steering and propelling apparatus the combination of two parallel. longitudinal pipes, terminating at their ends in propelling ets, their front ends turned 01 1twardly forming steering jets, with a pipe running at right angles iii-said lon i- "tu mal pi es, andc'ommuniceting with t-e same, sei pipe provided with pumps adapted and for the purpose of drawin Water into "said pipes', said lpngitudine pipes further provided near their rear ends with pipes at right angles thereto and communicating therewith, said last mentioned pipes terminating at the sides of the bees in steering 'jets, all of said pipes being provided with a series of'gate valves, 2i series of check valves and a series of hand valves, substantiallyes shown and described.
